ABSTRACT
The authors present a simple analytic model that
explicitly separates the controllable factors that
influence delays and propagation of delays in the
National Airspace System (NAS) from those factors
that are random variables in a given scenario. In
this paper, the controllable type of factor will be
called "fixed" and the random type of factor will be
called "variable." Simple relationships exist among
the fixed and variable factors that characterize NAS
delay propagation. We show how the model can
be applied to better understand delay propagation
from specific NAS airports, especially the effects of
flight schedule parameters on measured delay.
Recorded data from actual NAS operations are used
to derive estimates on key model parameters and to
show how delay characteristics vary among
different airports.
